Fluids are among the most effective agents for the transport of material in the Earth’s crust and, possibly, the upper mantle. Aqueous, hydrothermal fluids are responsible for the formation of most ore deposits and for much of the control of sea water chemistry. In addition, fluids play a ...
But the change range ofδ(34S) in the ore is larger than that of other tectono-alteration gold deposits in world, we infer it maybe the result of the ore-forming fluids mixed by crust and mantle (Talbe 1). 硫磺isotope.δ(硫铁矿) 34S在矿石是从1.37×10 3to +11.03×10-3,相同与...
Acidic fluids in the Earth’s lower crust Article Open access 27 October 2021 Introduction During subduction, the increase of pressure and temperature conditions in the subducting plate results in hydrous mineral breakdown and the release of volatile-rich fluids. The oxidized or reduced nature of ...
Subsurface mineral fluids and the substances recovered from them constitute a major part of the value of all minerals produced in this country, increasing from about 48 per cent in 1946 to 58 per cent in 1961, not including ground water. Each mineral fluid has its own preferred habitats, and...
These deposits formed in the metamorphic terrains of convergent plate boundaries and are controlled by ductile–brittle fracture structures (Goldfarb et al., 2001, 2005), with low-salinity H2O–CO2–CH4 ore-forming fluids (Groves et al., 1998, Groves et al., 2003, Bierlein and Crowe, 2000,...
Magmatic arcs above subduction zones produce most of the world’s explosive volcanism and host giant ore deposits of copper, molybdenum, gold and other valuable metals. Arc magmas are considerably more oxidized than mid-ocean ridge basalts1,2,3,4,5and generate volcanic eruptions that can inject ...
Cassiterite (SnO2) is the main ore mineral of tin in magmatic–hydrothermal tin deposits, but tin transport and precipitation mechanisms from hydrothermal fluids remain poorly understood. We critically evaluated aqueous tin speciation in hydrothermal fluids from extensive experimental data and thermodynamic ...
